The elements in the same group as arsenic are nitrogen, phosphorous, antimony, and bismuth. Also, arsenic is a metalloid, a classification which includes boron, silicon, germanium, antimony, tellurium, and polonium. These are elements with intermediate or mixed properties between metals and non-metals.

According to the Periodic Table in the Related Link, they are: Aluminum, Gallium, Germanium, Indium, Tin, Antimony, Thallium, Lead, Bismuth, and Polonium.
The 15th group elements are nitogen, phosphorus ,arsenic , antimony and bismuth.
There are 4 nitrogen family elements that are solid at room temperature: phosphorus, arsenic, antimony and bismuth.
Bismuth has a lower boiling point than antimony because bismuth has a larger atomic radius and weaker metallic bonding, which makes it easier for bismuth atoms to escape into the gas phase at a lower temperature. Antimony, on the other hand, has a smaller atomic radius and stronger metallic bonding, requiring more energy to break the bonds and reach its boiling point temperature.

Nitrogen is in the Group 15, along with the elements Phosphorous, Arsenic, Antimony, Bismuth, and Ununpentium.
Copper, Arsenic, Antimony , Zinc, Bismuth, and Platinum. Yes, that is 6.
The 15th group of elements in the periodic table is known as the Pnictogens or Nitrogen family. It includes nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). These elements share similar chemical properties, particularly in their ability to form compounds with five valence electrons.
The metalloids are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium. They are all located around a "stairstep" (called that because it is that sort of pattern) on the Periodic Table, between the metals and the nonmetals.
